In the Android system, the status bar notification is an important function, and the system or the application program sends a notification message through the notification service of the system to remind the user. Notification, that is, notification, is a notification with a global effect. It is displayed on the top of the screen in the form of an icon. When the user slides down, the specific content of the notification is displayed. Notification is generally done by sending a Notification object through NotificationManagerService. Among them, NotificationManagerService is a system-level service, located in the framework layer of the application program, and the application program sends global notifications to the system through the interface function NotificationManager.notify(). Specifically, when sending a notification, you need to create a Notification object to carry the content of the notification. This object will not be obtained directly through the construction method of Notification, but through the class Notification.Builder to instantiate a Builder object to set the properties of the notification, and through Notification The .Builder.builder() method gets a Notification object, and then uses the Notification object to send a notification through the method NotificationManager.notify(). Among them, the properties of the notification set by the Notification object include icon, text, prompt sound, vibration, light and so on.

In order to take over the above-mentioned NotificationManagerService service, the present invention injects a corresponding control module into the rooted Android system, so as to realize the management of the notification message sent by the application program.

As we all know, Root authority refers to the system administrator authority of Unix-like operating systems (including Linux, Android), similar to the Administrator (administrator) authority in Windows (Windows) system; Root authority can access and modify almost All files (Android system files and user files, excluding ROM). In view of this, the industry provides a variety of privilege escalation schemes to obtain the Root privilege of the Android system, realize user privilege escalation, and achieve the purpose of fully controlling the operating system. These privilege escalation schemes, according to the life cycle of privileges after privilege escalation, include permanent root privileges and temporary root privileges. As the name implies, in the case of permanent root privileges, once the application is root-authorized, there is no need to perform root privilege escalation in the future; and In the case of temporary root authority, the life cycle of the authority is only a process from booting to shutting down of the operating system, and rooting is still required for the next boot.

Regardless of the root method adopted, the basic principle of privilege escalation is to implant su to the system to receive permission requests, and then combine the SuperUser.apk application to realize human-computer interaction. Through the mutual interaction between su and SuperUser.apk Cooperate to achieve effective rights management. The present invention obtains the Root authority so as to inject the control module into the system, so as to take over the original system notification bar service NotificationManagerService, and monitor the behavior of sending notifications by the application program. However, which Root method is adopted is not a limitation of the present invention.

Based on the above principles, as shown in FIG. 1, the present invention provides a method for controlling application message display, which includes the following steps:

S11. Injecting into the system and running a control module for taking over the system notification bar service;

In order to control the notification bar message sent by the application program, the user can be selectively provided with the notification bar message, and the control module used to take over the system notification bar service, that is, the control module that takes over the NotificationManagerService, can be injected into the system. The embodiment of the present invention adopts the method of injecting the so file The control module is implanted into the rooted Android system in the following way, and the specific injection process is as follows:

First, suspend the system service process, that is, suspend the target process;

Then, the library file of the modified system service process is covered with the original library file; wherein, the functions in the modified library file include the function code, jar package, .so file, etc. of the control module of the present invention. Therefore, the monitoring module is injected into the system service process to monitor specific operations of other designated service processes.

The code of the control module is injected and runs in the SystemServer process, thereby taking over the system notification bar service, and monitoring the behavior of the application program sending the notification bar message. When an application program calls the interface function NotificationManager.notify(int id, Notification notification) to send a notification to the NotificationManagerService, the control module intercepts it to obtain a message identifier and a message object, wherein the message identifier id is used for recording The storage address of the message object in the memory, and the message object notification is used to record information such as message content and attributes sent by the application.

S12. The control module filters the notification bar messages sent by the application program according to preset conditions to determine the notification bar messages that are allowed to be displayed;

The notification bar messages sent by the application are filtered according to preset conditions, so as to determine the notification bar messages that are allowed to be displayed. In a specific embodiment, the preset condition may be constructed by a whitelist set by the user, that is, applications belonging to the whitelist are allowed to display notification bar messages sent by them. Users can set important application software as a white list, such as online banking and other software. Accept the instruction of the user to set the white list, and record the package names of the applications selected by the user in a list to allow these applications to display the notification bar messages sent by them. Provide the user with an interface for setting the whitelist, displaying all applications in turn, and each application provides a button for accepting the user's selection operation to add it to the whitelist. The white list can also be transmitted to the cloud server through a remote port, corresponding to the pre-allocated memory stored in the server corresponding to the third-party application account.

In other specific embodiments, the preset condition may be constructed by a blacklist set by the user, that is, applications belonging to the blacklist are prohibited from displaying notification bar messages sent by them. Users can set a blacklist for some application software that often displays advertisement notification bar messages. Accept the instruction of the user to set the blacklist, and record the package names of the applications selected by the user in a list to prohibit these applications from displaying the notification bar messages sent by them. Provide the user with an interface for setting the blacklist, displaying all applications in turn, and each application provides a corresponding button for accepting the user's selection operation to add it to the blacklist. The blacklist can also be transmitted to the cloud server through a remote port, corresponding to the pre-allocated memory stored in the server corresponding to the third-party application account.

In other embodiments, the cloud server configures the whitelist and/or blacklist, and pushes the whitelist and/or blacklist through a remote port. Use dynamic analysis method or static analysis method to analyze and determine the security of the application program, wherein,

The specific operation of the static analysis method is: extract the feature information of the installation file, such as package name, version number, MD5 signature, code, character string and other information, and match the feature codes in the feature code database of the cloud server one by one, according to Matching determines the judgment information representing the security of the installation file, that is, the security level information, and determines whether the installation file is safe according to the security level. Wherein, the feature code database records the mapping relationship between feature code information and the security level corresponding to the feature code information.

The specific operation of the dynamic analysis method is: parsing the installation file, creating a virtual machine environment corresponding to the application program running environment, monitoring the dynamic behavior and network exchange information of the application program running on the virtual machine, and determining the representative installation file according to the monitoring results The security judgment information, that is, the security level information, determines whether the installation file is safe according to the security level.

After the above static analysis or dynamic analysis, the names of the application packages that are determined to be safe are recorded in the white list, and the names of the application packages that are determined to be unsafe are recorded in the black list. Push the corresponding whitelist and/or blacklist through the remote port to allow or prohibit the display of notification bar messages sent by applications recorded in the whitelist or blacklist.

The cloud server can also put the applications in the sandbox into the blacklist and push them. The sandbox is a virtual software that directs the files generated and modified by the application to its own folder through redirection technology. The cloud server will isolate some applications with uncertain security, make them run in a virtual environment, and isolate them from the real system environment, so as to avoid threats to the system. Therefore, the cloud server puts the application program in the sandbox into the blacklist to prohibit it from displaying the notification bar message sent.

In other embodiments, by determining whether the application program is safe, it is determined whether to allow it to display the sent notification bar message. Call the security software to scan it, if the scanning result confirms that it is safe, it is allowed to display the notification bar message sent, otherwise it is not allowed.

In other embodiments, the cloud server determines whether to allow the application program to display the sent notification bar message by counting the number of users allowed to display the notification bar message. If the counted number of users is higher than the preset value, it is allowed to display the sent notification bar message and added to the whitelist, otherwise it is not allowed and added to the blacklist.

According to the preset conditions of the above structure, the notification bar messages sent by all the application programs installed in the user system are filtered to determine the notification bar messages that are allowed to be displayed.

S13. The control module only sends a message instruction to display the message in the notification bar that is allowed to be displayed to the SystemUI, so that the SystemUI only displays the message in the notification bar that is allowed to be displayed.

For versions after Android 2.2, the status bar and drop-down notification bar interface controls that originally existed in framework-res.apk are divided into a separate apk file and saved in the System/app folder. SystemUI.apk includes status bar icons, XML, control files, etc. The purpose of separating SystemUI.apk is to modify it more conveniently to meet the design needs of developers. Among them, SystemUI includes two modules of USB and Statusbar, and the status bar is mainly used to display some system icons, system time, application notification icons, application notification content and other information. Among them, the Statusbar module is used to control and manage the status bar.

Both the status bar and the toast can play the role of notification and reminder, but the implementation principles and manifestations of the two are different. Toast is equivalent to a Widget component, similar to a dialog box without buttons. The status bar can interact with other applications in the system, display notification bar messages sent by other applications, and can remind and notify the user without using the Activity.

Specifically, the NotificationManagerService calls the notifiy method to send notifications, interacts with the StatusBarManagerService through the Binder mechanism, and passes the sent notifications to the StatusBarManagerService, and the service calls the addNotification method to display the notification message. Among them, addNotificationViews(keys, notification) is used to display icons, tick(notification) is used to display message content. In the embodiment of the present invention, the control module takes over the NotificationManagerService, and intercepts the behavior of the application program calling the notify method to send notifications. Specifically, the behavior of the application program sending notification bar messages can be canceled by calling the cancel function, so as to prohibit the display of notification bar messages s application. You can also use the message identifier and message object corresponding to the notification bar message of the application that is determined to be displayed as a parameter to replace the corresponding parameter of the notification bar message of the application that is not allowed to be displayed, so as to pass the parameter through the notifiy method to display the message that is allowed to be displayed. Notification bar messages, hide notification bar messages that are not allowed to be displayed. Thus, the control module calls the notifiy method to send a message instruction for displaying a message notification bar to the SystemUI by restricting the application program of the message that is prohibited from being displayed, and only sends a message instruction for displaying the message in the notification bar message that is allowed to be displayed to the SystemUI, so that SystemUI only displays the notification bar messages that are allowed to be displayed.

In addition, a message management interface is provided corresponding to all notification bar messages sent by all applications, and in response to user viewing instructions, all notification bar messages sent by applications without filtering are displayed through the message management interface, including allowing display The notification bar message and the notification bar message that are not allowed to be displayed.

Referring to FIG. 2, the present invention also provides an application program message display control device, including an injection unit 11, a filter unit 12, and a display unit 13, wherein,

The injection unit 11 is used for injecting into the system and running a control module for taking over the system notification bar service;

In order to control the notification bar message sent by the application program, the notification bar message can be selectively provided to the user, and the injection unit 11 injects into the system a control module for taking over the notification bar service of the system, that is, a control module for taking over NotificationManagerService, the embodiment of the present invention The injection unit 11 implants the control module into the Android system after rooting by injecting the so file, and the specific injection process is as follows:

First, suspend the system service process, that is, suspend the target process;

Then, the library file of the modified system service process is covered with the original library file; wherein, the functions in the modified library file include the function code, jar package, .so file, etc. of the control module of the present invention. Therefore, the monitoring module is injected into the system service process to monitor specific operations of other designated service processes.

The code of the control module is injected and runs in the SystemServer process, thereby taking over the system notification bar service, and monitoring the behavior of the application program sending the notification bar message. When an application program calls the interface function NotificationManager.notify(int id, Notification notification) to send a notification to the NotificationManagerService, the control module intercepts it to obtain a message identifier and a message object, wherein the message identifier id is used for recording The storage address of the message object in the memory, and the message object notification is used to record information such as message content and attributes sent by the application.

The filtering unit 12 is used for the control module to filter notification bar messages sent by applications according to preset conditions to determine the notification bar messages that are allowed to be displayed;

The filtering unit 12 filters the notification bar messages sent by the application program according to preset conditions, so as to determine the notification bar messages that are allowed to be displayed. In a specific embodiment, the preset condition may be constructed by a whitelist set by the user, that is, the filtering unit 12 allows applications belonging to the whitelist to display notification bar messages sent by them. Users can set important application software as a white list, such as online banking and other software. Accept the instruction of the user to set the white list, and record the package names of the applications selected by the user in a list to allow these applications to display the notification bar messages sent by them. Provide the user with an interface for setting the whitelist, displaying all applications in turn, and each application provides a button for accepting the user's selection operation to add it to the whitelist. The white list can also be transmitted to the cloud server through a remote port, corresponding to the pre-allocated memory stored in the server corresponding to the third-party application account.

In other specific embodiments, the preset condition may be constructed by a blacklist set by the user, that is, applications belonging to the blacklist are prohibited from displaying notification bar messages sent by them. Users can set a blacklist for some application software that often displays advertisement notification bar messages. Accept the instruction of the user to set the blacklist, and record the package names of the applications selected by the user in a list to prohibit these applications from displaying the notification bar messages sent by them. Provide the user with an interface for setting the blacklist, displaying all applications in turn, and each application provides a corresponding button for accepting the user's selection operation to add it to the blacklist. The blacklist can also be transmitted to the cloud server through a remote port, corresponding to the pre-allocated memory stored in the server corresponding to the third-party application account.

In other embodiments, the cloud server configures the whitelist and/or blacklist, and pushes the whitelist and/or blacklist through a remote port. Use dynamic analysis method or static analysis method to analyze and determine the security of the application program, wherein,

The specific operation of the static analysis method is: extract the feature information of the installation file, such as package name, version number, MD5 signature, code, character string and other information, and match the feature codes in the feature code database of the cloud server one by one, according to Matching determines the judgment information representing the security of the installation file, that is, the security level information, and determines whether the installation file is safe according to the security level. Wherein, the feature code database records the mapping relationship between feature code information and the security level corresponding to the feature code information.

The specific operation of the dynamic analysis method is: parsing the installation file, creating a virtual machine environment corresponding to the application program running environment, monitoring the dynamic behavior and network exchange information of the application program running on the virtual machine, and determining the representative installation file according to the monitoring results The security judgment information, that is, the security level information, determines whether the installation file is safe according to the security level.

After the above static analysis or dynamic analysis, the names of the application packages that are determined to be safe are recorded in the white list, and the names of the application packages that are determined to be unsafe are recorded in the black list. The corresponding whitelist and/or blacklist are pushed through the remote port, and the filtering unit 12 allows or prohibits display of notification bar messages sent by applications recorded in the whitelist or blacklist based on the whitelist and/or blacklist.

The cloud server can also put the applications in the sandbox into the blacklist and push them. The sandbox is a virtual software that directs the files generated and modified by the application to its own folder through redirection technology. The cloud server will isolate some applications with uncertain security, make them run in a virtual environment, and isolate them from the real system environment, so as to avoid threats to the system. Therefore, the cloud server puts the application program in the sandbox into the blacklist to prohibit it from displaying the notification bar message sent.

In other embodiments, by determining whether the application program is safe, it is determined whether to allow it to display the sent notification bar message. Call the security software to scan it, if the scanning result confirms that it is safe, it is allowed to display the notification bar message sent, otherwise it is not allowed.

In other embodiments, the cloud server determines whether to allow the application program to display the sent notification bar message by counting the number of users allowed to display the notification bar message. If the counted number of users is higher than the preset value, it is allowed to display the sent notification bar message and added to the whitelist, otherwise it is not allowed and added to the blacklist.

According to the preset conditions of the above structure, the filtering unit 12 filters the notification bar messages sent by all the application programs installed in the user system, and determines the notification bar messages that are allowed to be displayed.

The display unit 13 is used for the control module to only send a message instruction to display the message in the notification bar that is allowed to be displayed to the systemUI, so that the systemUI only displays the message in the notification bar that is allowed to be displayed.

For versions after Android 2.2, the status bar and drop-down notification bar interface controls that originally existed in framework-res.apk are divided into a separate apk file and saved in the System/app folder. SystemUI.apk includes status bar icons, XML, control files, etc. The purpose of separating SystemUI.apk is to modify it more conveniently to meet the design needs of developers. Among them, SystemUI includes two modules of USB and Statusbar, and the status bar is mainly used to display some system icons, system time, application notification icons, application notification content and other information. Among them, the Statusbar module is used to control and manage the status bar.

Both the status bar and the toast can play the role of notification and reminder, but the implementation principles and manifestations of the two are different. Toast is equivalent to a Widget component, similar to a dialog box without buttons. The status bar can interact with other applications in the system, display notification bar messages sent by other applications, and can remind and notify the user without using the Activity.

Specifically, the NotificationManagerService calls the notifiy method to send notifications, interacts with the StatusBarManagerService through the Binder mechanism, and passes the sent notifications to the StatusBarManagerService, and the service calls the addNotification method to display the notification message. Among them, addNotificationViews(keys, notification) is used to display icons, tick(notification) is used to display message content. In the embodiment of the present invention, the control module takes over the NotificationManagerService, and intercepts the behavior of the application program calling the notify method to send notifications. Specifically, the behavior of the application program sending notification bar messages can be canceled by calling the cancel function, so as to prohibit the display of notification bar messages s application. It is also possible to use the message identifier and message object corresponding to the notification bar message of the application that is determined to be displayed as parameters to replace the corresponding parameters of the notification bar message of the application program that is not allowed to be displayed, so that the parameter is passed through the notifiy method to make the display unit 13 Display the notification bar messages that are allowed to be displayed, and hide the notification bar messages that are not allowed to be displayed. Thus, the control module calls the notifiy method to send a message instruction to display the message notification column to the SystemUI of the display unit 13 by restricting the application program of the message that is prohibited from being displayed, and only sends a notification that displays the display permission to the SystemUI of the display unit 13. The message command of the bar message, so that the SystemUI of the display unit 13 only displays the notification bar message that is allowed to be displayed.

In addition, corresponding to all notification bar messages sent by all application programs, the display unit 13 provides a message management interface, in response to the user's viewing instruction, through the message management interface, unfiltered all notification bar messages sent by the application programs are displayed , including notification bar messages that are allowed to be displayed and notification bar messages that are not allowed to be displayed.

To sum up, the present invention injects into the control module, so that the control module controls the display of the notification bar message sent by the application program, and only displays the notification bar that is allowed to be displayed based on the user preset and/or the black and white list pushed by the cloud server Messages, hide notification bar messages that are not allowed to be displayed, and selectively display notification bar messages to users, which not only avoids frequent pop-ups of useless messages that interfere with users, but also does not lose useful messages, which is more in line with user needs and improves user experience. .

The above descriptions are only part of the embodiments of the present invention. It should be pointed out that those skilled in the art can make some improvements and modifications without departing from the principles of the present invention. It should be regarded as the protection scope of the present invention.
